A New Laser Crystal for Holographic Interferometry

9362063尼科尔森建议开发一种新的激光晶体--氟化钇锂，用于全息干涉计量学。目前，大多数脉冲激光全息干涉测量是使用倍频的NdYAG或红宝石激光器进行的。这两种晶体中的任何一种都存在一些限制，其中一些限制将被新提议的晶体克服。全息还预计，这种晶体将在医学和其他领域有重要应用。全息图像学计划在第一阶段证明Pr晶体的某些方面，例如制造种子激光器和在注入种子高斯镜像振荡器中获得单纵模。将尝试使用荧光转换器和掺杂玻璃转换器来提高泵浦效率。***

9362063 Nicholson A new laser crystal, praeseodymium yttrium lithium fluoride, is being proposed for development for applications in holographic interferometry. Most pulsed laser holographic interferometry is presently performed with either frequency doubled neodymium yag or with ruby lasers. There are a number of limitations imposed by either of these tow crystals, some of which will be overcome by the new proposed crystal. Holographic also anticipates the crystal will have significant applications in medicine and elsewhere. Holographics proposes to prove certain aspects of the praseodymium crystal in Phase I, such as making a seed laser and gaining single longitudinal mode in an injection seeded gaussian mirrored oscillator. Improvements in pumping efficiency will be attempted by using fluorescent converter and doped glass converters. ***
